In this work, mechanical testing methods are performed to understand the effect of Arcam-deposited Ti-6Al-4V solidification microstructure on mechanical properties. It is critical to know the extent to which as-built microstructure will affect the mechanical properties of an additively manufactured Ti-6Al-4V part for process qualification. To achieve this goal, the solidification microstructure is varied systematically in the test samples by varying the process parameters, building on related research mapping microstructure to process parameters. Optical microscopy and EBSD techniques are used to determine the prior-beta colony size and alpha lath dimensions in different test samples. These findings from microstructural characterization are then related to results from mechanical tests. A method to utilize the primary process parameters to control the mechanical properties of the as-built part through microstructure control is presented.
